Whole-Home Repiping for Mississauga Homes

When to call about whole-home repiping

Galvanized steel supply pipe was common in houses built before the 1960s. It rusts from the inside, narrowing until a shower barely sputters. Polybutylene, the grey plastic pipe sold in the 1980s and early 1990s, is known for brittle fittings and sudden failures. Older copper can also wear thin, especially near fittings, after decades of fast-moving water.

Call us when pressure has dropped across the whole house, when pinholes have opened twice or more in twelve months, when water runs brown after sitting, or when a home inspection flags poly-b or galvanized pipe.

Common causes we find

• Galvanized lines choked with rust and scale.
• Poly-b with failing crimp fittings or cracks near connections. Read about it on our poly-b replacement page.
• Copper with repeated pinholes from erosion or poor grounding practices.
• Mixed systems patched over the years, with dissimilar metals joined directly.

Our process on the day

Repiping takes several days in most houses, not one. Before work starts, we walk the house with you and map where lines run, which fixtures they feed, and where we will need access. We choose between copper and PEX based on the layout, your preference, and what makes sense for access.

1. Floors and furniture are protected along our route.
2. Small access openings are made in walls or ceilings where lines must be fished. We keep them as few and as small as practical.
3. New lines are run, connected to fixtures, and fitted with proper shut-offs.
4. The system is pressure tested before any opening is closed.
5. Water is usually restored at the end of each working day so the house stays livable.

Repair or replace?

Not every house with old pipe needs a full repipe. If the trouble is in one run, such as a kitchen line or a single bathroom branch, replacing that section may be enough for now. We will show you the pipe we can see and give you honest options at more than one level. A permit may be required for the work, and we will tell you if so.

Fixtures are often swapped at the same time; our faucet repair and replacement page covers that side.

Keeping it from coming back

New pipe lasts a long time when it is left alone. Keep pressure in a sensible range; a pressure-reducing valve helps where street pressure is high. Insulate lines on exterior walls. Have the main shut-off checked so it works when you need it.

Supply pipes are only half the picture. If you have an older home with mature trees, the drain side deserves attention too; see our note on tree roots and sewers.
